The KOYO 6210ZZ is a single-row deep groove ball bearing with double metal shields (ZZ) – measuring 50mm bore x 90mm outside diameter x 20mm width.
Load ratings: dynamic 43.9 kN (Cr) and static 23.3 kN (C0r) – fatigue load limit 1.55 kN. Limiting speed 7100 rpm with grease lubrication and 8500 rpm with oil lubrication. Minimum fillet radius 1.1mm.
Deep groove ball bearings are the most widely used bearing type – carrying radial and axial loads in both directions with low friction and high running accuracy. The metal shields retain the factory-filled grease and keep out dust and debris while allowing higher speeds than a contact seal.
Manufactured by KOYO (JTEKT) in chrome steel to ISO standards.
